If you used oil, you could build something smaller (at least if you
don't count the tank). The 2nd cluster gets sufficient cooling from the
natural convection which develops in the channel (no forced convection).
The same would hold for water. It would be fun to try, but I think air
is more convenient. But even with air you can build small systems. Check
our "third HTPC", which would be hard to build much smaller even with
water-cooling (or oil for that matter).
